Let her go
From Lord Of Utterdom
"I don't need anything in return," you say, waving your hand towards the dungeon's exit. "I do what is right for the sake of what is right."
She seems genuinely shocked that you don't ask for anything, but bows graciously.
"Thank you," she says. "I mean that. Thank you."
She heads for the door, stopping only to speak to you once more.
"I will mend my ways and be trouble no more. It will be all I can do to repay your kindness. Thank you, great Prince."
She heads out the door, leaving you with an incredible feeling of having done the right thing.
Head out and go elsewhere amongst the castle
